No, bitcoin is quite vulnerable, especially with some of the latest updates. The new transaction reverse feature is so easily abused as to be worthless. I can 'buy' something with bitcoin and then reverse the transaction. You're shit out of money, shit out of product, and shit out of luck. No real chance of recourse.
Can you link to what you are talking about? I thought the only way to actually reverse a transaction in Bitcoin would be to control 51% of the hashing power in the system. (i.e. generate a longer blockchain without that transaction which would invalidate the block with the transaction)
